APPARATUS FOR MANUFACTURING DRESS-SUITCASES.

Specification of Letters Eatent. Pittetlted NOV. 16, 1920.

Application filed October 19, 1917. Serial No. 197,478.

To all whom it may concern:

Be it known that l, HENRY L. PLUMMER, a citizen of the United states.residing at .letersburg, in the county of Dinwiddie and State of\Virginia, have invented certain new and useful Improvements inApparatus for Manufacturing Dresstluitcases; and I do hereby declare thefollowing; to be a full, clear, and exact description. of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to paper bOX and like constructions and moreparticularly to the construction of elements in the erection of suitcases.

It is one of the objects of the present invention to provide a processfor the manufacture and also to provide an apparatus for the practice ofthe process whereby the principal bottom or body member of dress suitcases, for instance, can be made economicallv, rapidly and accurately.and particularly to provide for the production of dress suit casebottoms of various sizes. It is another object of the present inventionto provide an a aratus, capable of ready adjustment to facilitate themanufacture of dress suit case bottoms or the like. and especially toprovide an apparatus having relativelv adjustable male and female cuttinmembers to facilitate the cutting of the blanks to the desired andrequisite outline.

Wi h the e and other obiects in view. the present invention consists inthe method of and apparatus for manufacturing blanks for boxconstructions and especially for the manufacture of dress suit caseelements, one form of apparatus for practising the method beingillustrated in the accompanyinc drawing. in which,

Figure 1 is a plan view of one form of blank,

Fig. 2 is a perspective view of the folded blank,

Fig. 3 is a plan view partly in section showing one part of a machine orapparatus for cutting the stock. and,

Fig. 4 is a vertical section partly in elevation of the apparatus.

The present invention contemplates particularly the production of thebottom or body element of a dress suit case. a form of which isillustrated in plan view in Fig. 1 and whi h is shown in folded positionin Fig. 2. The blank comprises a substantially oblong central panel" 2which? may be of suitable proportions and is foldable along lines A andB, the outer portions 3 and l forming the sides of the box element,these latter sides being foldable on lines 0 and d to form flange 0 and.are similarly foldable at their ends to form flanges 7 the bot tom 2having also end flanges 9. The com mon practice in. the manufacture ofboxes of this type in order to facilitate the proper foldin -of thebottom memberhas been to nick Irom corners h-h of one side of apreviously cut blank chips forming notches of suitable outline and thento transfer the blank from which the corner notches have been chipped orcut to another machine and then to cut out the intermediate angularchips forming notches i-2'. In this practice, the corner notches hh atone side of the bottom, have been cut out and the blank turned side forside and the other corners chipped out. One of the particular objects ofpresent invention is to provide a process for manufacturing these blankswhich contemplates simultaneously cutting the required notchesthroughout the entire blank at one single step or if preferred, may bepractised by the cutting of all of the notches h-h and z'i at one sideonly of the blank which then may be reversed side for side and all ofthe notches at the other side cut.

T o se"ure this step in the manufmture of the box bottom, I utilize asuitable form of cutting or punching mechanism provided withsuitablecorner cutters H and movable toward and cooperable with femalecutters H and having also male and female intermechate notch cutters Iand I. The several male cutters adjustably attached by bolts or otherfastening means 10 to a head 11 or carrier which may be operated in anysuitable manner toward and from a bed or support 12 upon which thecomplementary female members are provided, these latter also beingrelatively adjustable to the'becl 12 and adapted to be S8"UICl thereonby bolts or other fastening means 10. One or the other of the members 11and 12. the latter in the present instance. is provided with a set ofedge gages 15 adjustably secured to the respective member as by bolts orscrews 16.

With this apparatus, the process of manufacturing a blank of the givensize is to set the edge gages 15 with respect to the several cutters, adistance suflicient to produce notches as /L-h and i of the requisitedepth into the edgeo'i' the blank andto set the respective cutters H-Hand the cut ters 1-1 in suitable disposition to each other by looseningup their fastening screws or bolts 10, these cutters being provided Withholders having means permitting relative adjustment to each other andshown in the present instance, as belngpr'ovi'ded with slots 10 throughwhich the bolts pass. Having adjusted the cutters with relation to eachother so as t'o' produce thenotches at the predetermined distances; theblank is then inserted until'it has a proper en-- gagement with the edgegages: 15 and then the apparatus operated so' that the'cutt'er's severthe chipspfrom the blank at theplaces predetermined;

While it is preferably that-the apparatus may beutilizedforcuttiugialtof thenotches in both edges of the blank at onetime, the

cutting. of one edge only may be practised, if it is desired, the formof the apparatus illustrated in Fig. 3 being but one-half of a duplicateset of cutters arranged at the opposite side of the apparatus, so thatall ofthe cuts may be made at one time.

What is claimed is:

An apparatus for notching the cut bodies of suit cases, comprising incombination, a tablegahead, adjustable end andsid'e stops mountedon oneof said members and a plurality of" complementary cutters, saidbutte'r's c'ompr1s1ng vertical and angular-1y dis posed cutting edges;bases perpendicular theieto and each provided with a slot whereby saidcutters may be independently adjusted, alined' and removably secured tosaid 'table andhead;

In" testimony whereof I afliXm-y signature.
